ANY TRANSFEREE OF THIS NOTE SHOULD CAREFULLY REVIEW THE TERMS OF THIS NOTE, INCLUDING SECTIONS 3(c)(iii) AND 19(a) HEREOF. THE PRINCIPAL AMOUNT REPRESENTED BY THIS NOTE AND, ACCORDINGLY, THE SECURITIES ISSUABLE UPON CONVERSION HEREOF MAY BE LESS THAN THE AMOUNTS SET FORTH ON THE FACE HEREOF PURSUANT TO SECTION 3(c)(iii) OF THIS NOTE.

FOR VALUE RECEIVED, ART Advanced Research Technologies Inc., a Canadian corporation (the "Company”), hereby promises to pay to the order of JGB CAPITAL L.P. or registered assigns (“Holder”) the amount set out above as the Principal (as reduced pursuant to the terms hereof pursuant to redemption, conversion or otherwise, the “Principal”) when due, whether upon the Maturity Date (as defined below), on any Installment Date with respect to the Installment Amount due on such Installment Date (each, as defined herein), acceleration, redemption or otherwise (in each case in accordance with the terms hereof) and to pay interest (“Interest”) on any outstanding Principal at the Interest Rate, from the date set out above as the Issuance Date (the “Issuance Date”) until the same becomes due and payable, whether upon an Interest Date (as defined below), any Installment Date or, the Maturity Date, acceleration, conversion, redemption or otherwise (in each case in accordance with the terms hereof). This Senior Secured Convertible Note (including all Senior Secured Convertible Notes issued in exchange, transfer or replacement hereof, this "Note”) is one of an issue of Senior Secured Convertible Notes issued pursuant to the Securities Purchase Agreement (as defined below) on the Closing Date (collectively, the “Notes” and such other Senior Secured Convertible Notes, the “Other Notes”). Certain capitalized terms used herein are defined in Section 31.

(1) PAYMENTS OF PRINCIPAL. On each Installment Date, the Company shall pay to the Holder an amount equal to the Installment Amount due on such Installment Date in accordance with Section 8. The “Maturity Date” shall be January 28, 2008, as the same may be extended at the option of the Holder (i) in the event that, and for so long as, an Event of Default (as defined in Section 4(a)) shall have occurred and be continuing or any event shall have occurred and be continuing which with the passage of time and the failure to cure would result in an Event of Default and (ii) through the date that is ten (10) days after the consummation of a Change of Control in the event that a Change of Control is publicly announced or a Change of Control Notice (as defined in Section 5(b)) is delivered prior to the Maturity Date.

(2) INTEREST; INTEREST RATE. Interest on this Note shall commence accruing on the Issuance Date and shall be computed on the basis of a 365-day year and actual days elapsed and shall be payable in arrears for each Calendar Quarter on the tenth (10^th) day of the succeeding Calendar Quarter during the period beginning on the Issuance Date and ending on, and including, the Maturity Date (each, an “Interest Date”) with the first Interest Date being October 10, 2005. Interest shall be payable on each Interest Date, to the record holder of this Note on the applicable Interest Date, in cash (“Cash Interest”) or, at the option of the Company, in Common Shares (“Interest Shares”) or a combination thereof, provided that the Interest which accrued during any period may be payable in Interest Shares if, and only if, (i) the Company delivers written notice (each, an “Interest Election Notice”) of such election to each holder of the Notes on or prior to the Interest Notice Due Date and (ii) the Interest Shares shall be eligible for sale without restriction and without the need for registration under any applicable federal or state securities laws. Each Interest Election Notice must specify the amount of Interest that shall be paid as Cash Interest, if any, and the amount of Interest that shall be paid in Interest Shares. Interest to be paid on an Interest Date in Interest Shares shall be paid in a number of fully paid and non-assessable (rounded to the nearest whole share in accordance with Section 3(a)) Common Shares equal to the quotient of (a) the amount of Interest payable on such Interest Date less any Cash Interest paid and (b) the Interest Conversion Price in effect on the applicable Interest Date. If any Interest Shares are to be paid on an Interest Date, then the Company shall (X) provided that the Company’s transfer agent (the “Transfer Agent”) is participating in the Depository Trust Company (“DTC”) Fast Automated Securities Transfer Program, credit such aggregate number of Interest Shares to which the Holder shall be entitled to the Holder’s or its designee’s balance account with DTC through its Deposit Withdrawal Agent Commission system, or (Y) if the foregoing shall not apply, issue and deliver on the applicable Interest Date, to the address set forth in the register maintained by the Company for such purpose pursuant to the Securities Purchase Agreement or to such address as specified by the Holder in writing to the Company at least three (3) Trading Days prior to the applicable Interest Date, a certificate, registered in the name of the Holder or its designee, for the number of Interest Shares to which the Holder shall be entitled. Notwithstanding the foregoing, the Company shall not be entitled to pay Interest in Interest Shares and shall be required to pay such Interest in cash as Cash Interest on the applicable Interest Date if, unless consented to in writing by the Holder, during the period commencing on the applicable Interest Notice Due Date through the applicable Interest Date the Equity Conditions have not been satisfied. Prior to the payment of Interest on an Interest Date, Interest on this Note shall accrue at the Interest Rate and be payable by way of inclusion of the Interest in the Conversion Amount in accordance with Section 3(b)(i). Upon the occurrence and during the continuance of an Event of Default, the Interest Rate shall be increased to twelve percent (12%). In the event that such Event of Default is subsequently cured, the adjustment referred to in the preceding sentence shall cease to be effective as of the date of such cure; provided that the Interest as calculated and unpaid at such increased rate during the continuance of such Event of Default shall continue to apply to the extent relating to the days after the occurrence of such Event of Default through and including the date of cure of such Event of Default.

(3) CONVERSION OF NOTES. This Note shall be convertible into the Company’s common shares (the “Common Shares”), on the terms and conditions set forth in this Section 3.

(a) Conversion Right. Subject to the provisions of Section 3(d), at any time or times on or after the Issuance Date, the Holder shall be entitled to convert any portion of the outstanding and unpaid Conversion Amount (as defined below) into fully paid and non-assessable Common Shares in accordance with Section 3(c), at the Conversion Rate (as defined below). The Company shall not issue any fraction of a Common Share upon any conversion. If any conversion would result in the issuance of a fraction of a Common Share, the Company shall round such fraction of a Common Share up to the nearest whole share.

(b) Conversion Rate. The number of Common Shares issuable upon conversion of any Conversion Amount pursuant to Section 3(a) shall be determined by dividing (x) such Conversion Amount by (y) the Conversion Price (the “Conversion Rate”).

(i) "Conversion Amount” means the sum of (A) the portion of the Principal to be converted, redeemed or otherwise with respect to which this determination is being made and (B) accrued and unpaid Interest with respect to such Principal.

(ii) "Conversion Price” means, as of any Conversion Date (as defined below) or other date of determination, Cdn $0.99, subject to adjustment as provided herein after the Subscription Date.

(i) Optional Conversion. To convert any Conversion Amount into Common Shares on any date (a “Conversion Date”), the Holder shall (A) transmit by facsimile (or otherwise deliver), for receipt on or prior to 5:00 p.m., New York Time, on such date, a copy of an executed notice of conversion in the form attached hereto as Exhibit I (the “Conversion Notice”) to the Company and (B) if required by Section 3(c)(iii), surrender this Note to a courier for delivery to the Company as soon as practicable on or following such date (or an indemnification undertaking with respect to this Note in the case of its loss, theft or destruction). On or before the first (1^st) Trading Day following the date of receipt of a Conversion Notice, the Company shall transmit by facsimile a confirmation of receipt of such Conversion Notice to the Holder and the Transfer Agent. On or before the first (1^st) Trading Day following the date of receipt of a Conversion Notice (the “Share Delivery Date”), the Company shall (X) provided that the Transfer Agent is participating in the DTC Fast Automated Securities Transfer Program, credit such aggregate number of Common Shares to which the Holder shall be entitled to the Holder’s or its designee’s balance account with DTC through its Deposit Withdrawal Agent Commission system or (Y) if the foregoing shall not apply, issue and deliver to the address as specified in the Conversion Notice, a certificate, registered in the name of the Holder or its designee, for the number of Common Shares to which the Holder shall be entitled. If this Note is physically surrendered for conversion as required by Section 3(c)(iii) and the outstanding Principal of this Note is greater than the Principal portion of the Conversion Amount being converted, then the Company shall as soon as practicable and in no event later than three (3) Trading Days after receipt of this Note and at its own expense, issue and deliver to the holder a new Note (in accordance with Section 19(d)) representing the outstanding Principal not converted. The Person or Persons entitled to receive the Common Shares issuable upon a conversion of this Note shall be treated for all purposes as the record holder or holders of such Common Shares on the Conversion Date. In the event of a partial conversion of this Note pursuant hereto, the principal amount converted shall be deducted from the Installment Amounts relating to the Installment Dates as set forth in the Conversion Notice.

(ii) Company’s Failure to Timely Convert. If within three (3) Trading Days after the Company’s receipt of the facsimile copy of a Conversion Notice the Company shall fail to issue and deliver a certificate to the Holder or credit the Holder’s balance account with DTC for the number of Common Shares to which the Holder is entitled upon such holder’s conversion of any Conversion Amount (a “Conversion Failure”), and if on or after such Trading Day the Holder purchases (in an open market transaction or otherwise) Common Shares to deliver in satisfaction of a sale by the Holder of Common Shares issuable upon such conversion that the Holder anticipated receiving from the Company (a “Buy-In”), then the Company shall, within three (3) Trading Days after the Holder’s request and in the Holder’s discretion, either (i) pay cash to the Holder in an amount equal to the Holder’s total purchase price (including brokerage commissions, if any) for the Common Shares so purchased (the “Buy-In Price"), at which point the Company’s obligation to deliver such certificate (and to issue such Common Shares) shall terminate, or (ii) promptly honor its obligation to deliver to the Holder a certificate or certificates representing such Common Shares and pay cash to the Holder in an amount equal to the excess (if any) of the Buy-In Price over the product of (A) such number of Common Shares, times (B) the Closing Bid Price on the Conversion Date.

(iii) Book-Entry. Notwithstanding anything to the contrary set forth herein, upon conversion of any portion of this Note in accordance with the terms hereof, the Holder shall not be required to physically surrender this Note to the Company unless (A) the full Conversion Amount represented by this Note is being converted or (B) the Holder has provided the Company with prior written notice (which notice may be included in a Conversion Notice) requesting reissuance of this Note upon physical surrender of this Note. The Holder and the Company shall maintain records showing the Principal and Interest converted and the dates of such conversions or shall use such other method, reasonably satisfactory to the Holder and the Company, so as not to require physical surrender of this Note upon conversion.

(iv) Pro Rata Conversion; Disputes. In the event that the Company receives a Conversion Notice from more than one holder of Notes for the same Conversion Date and the Company can convert some, but not all, of such portions of the Notes submitted for conversion, the Company, subject to Section 3(d), shall convert from each holder of Notes electing to have Notes converted on such date a pro rata amount of such holder’s portion of its Notes submitted for conversion based on the principal amount of Notes submitted for conversion on such date by such holder relative to the aggregate principal amount of all Notes submitted for conversion on such date. In the event of a dispute as to the number of Common Shares issuable to the Holder in connection with a conversion of this Note, the Company shall issue to the Holder the number of Common Shares not in dispute and resolve such dispute in accordance with Section 24.

(i) Beneficial Ownership. Notwithstanding anything contained herein to the contrary, the Company shall not effect any conversion of this Note, and the Holder of this Note shall not have the right to convert any portion of this Note pursuant to Section 3(a) that would be convertible into that number of Common Shares which, when added to the number of Common Shares otherwise beneficially owned by the Holder including those issuable upon the exercise of convertible securities, warrants or options held by the Holder, would exceed 4.99% (the “Maximum Percentage”) of the outstanding Common Shares at the time of conversion. For purposes of this Section 3(d)(i), beneficial ownership shall be calculated in accordance with Section 13(d) of the Securities Exchange Act of 1934, as amended. For purposes of this Section 3(d)(i), in determining the number of outstanding Common Shares, the Holder may rely on the number of outstanding Common Shares as reflected in (x) the Company’s most recent Form 20-F or Form 6-K, as the case may be (y) a more recent public announcement by the Company or (z) any other notice by the Company or the Transfer Agent setting forth the number of Common Shares outstanding. For any reason at any time, upon the written or oral request of the Holder, the Company shall within one (1) Trading Day confirm orally and in writing to the Holder the number of Common Shares then outstanding. In any case, the number of outstanding Common Shares shall be determined after giving effect to the conversion or exercise of securities of the Company, including this Note, by the Holder or its affiliates since the date as of which such number of outstanding Common Shares was reported. By written notice to the Company, the Holder may increase or decrease the Maximum Percentage to any other percentage not in excess of 9.99% specified in such notice; provided that (i) any such increase will not be effective until the sixty-first (61^st) day after such notice is delivered to the Company, and (ii) any such increase or decrease will apply only to the Holder and not to any other holder of Notes.

(ii) Principal Market Regulation. The Company shall not be obligated to issue any Common Shares upon conversion of this Note if the issuance of such Common Shares would exceed the aggregate number of Common Shares which the Company may issue upon conversion or exercise, as applicable, of the Notes and Warrants and the payment of Interest in Interest Shares without breaching the Company’s obligations under the rules or regulations of the Principal Market (the "Exchange Cap”). The Company shall seek the approval of the Principal Market, and shall seek the approval of its shareholders as may be required by the applicable rules of the Principal Market, for issuances of Common Shares in excess of the Exchange Cap. Once the Company has obtained the approval or approvals required by the foregoing sentence, the Exchange Cap shall no longer be applicable. Until such approval is obtained, no purchaser of the Notes pursuant to the Securities Purchase Agreement (the “Purchasers”) shall be issued in the aggregate, upon conversion or exercise, as applicable, of Notes or Warrants or the payment of Interest in Interest Shares, Common Shares (as adjusted for share splits, share dividends, share combinations and other similar transactions) in an amount greater than the product of the Exchange Cap multiplied by a fraction, the numerator of which is the principal amount of Notes issued to the Purchasers pursuant to the Securities Purchase Agreement on the Closing Date and the denominator of which is the aggregate principal amount of all Notes issued to the Purchasers pursuant to the Securities Purchase Agreement on the Closing Date (with respect to each Purchaser, the “Exchange Cap Allocation”). In the event that any Purchaser shall sell or otherwise transfer any of such Purchaser’s Notes, the transferee shall be allocated a pro rata portion of such Purchaser’s Exchange Cap Allocation, and the restrictions of the prior sentence shall apply to such transferee with respect to the portion of the Exchange Cap Allocation allocated to such transferee. In the event that any holder of Notes shall convert all of such holder’s Notes into a number of Common Shares which, in the aggregate, is less than such holder’s Exchange Cap Allocation, then the difference between such holder’s Exchange Cap Allocation and the number of Common Shares actually issued to such holder shall be allocated to the respective Exchange Cap Allocations of the remaining holders of Notes on a pro rata basis in proportion to the aggregate principal amount of the Notes then held by each such holder.

(e) Restrictive Legends. Any Common Shares issued upon conversion of this Note shall bear the restrictive legends referred to in Sections 2(g) and 2(h) of the Securities Purchase Agreement, to the extent required thereby.

(a) Event of Default. Each of the following events shall constitute an “Event of Default”:

(i) the failure of the Common Shares issued upon conversion or as part of any Installment Amount to be freely tradable on or prior to the Effectiveness Time, or, after the Effectiveness Time, the Common Shares of any holder of Notes shall cease to be freely tradable and such lapse continues for a period of fifteen (15) consecutive days or for more than an aggregate of thirty (30) days in any 365-day period;

(ii) the suspension from trading or failure of the Common Shares to be listed on an Eligible Market for a period of five (5) consecutive Trading Days or for more than an aggregate of fifteen (15) Trading Days in any 365-day period;

(iii) the Company’s (A) failure to cure a Conversion Failure by delivery of the required number of Common Shares within ten (10) Trading Days after the applicable Conversion Date or (B) notice, written or oral, to any holder of the Notes, including by way of public announcement or through any of its agents, at any time, of its intention not to comply with a request for conversion of any Notes into Common Shares that is tendered in accordance with the provisions of the Notes;

(iv) at any time following the tenth (10^th) consecutive Trading Day that the number of Common Shares that are available for issuance to the Holder is less than the number of Common Shares that the Holder would be entitled to receive upon a conversion of the full Conversion Amount of this Note (without regard to any limitations on conversion set forth in Section 3(d) or otherwise);

(v) the Company’s failure to pay to the Holder any amount of Principal, Interest or other amounts when and as due under this Note (including, without limitation, the Company’s failure to pay any redemption payments) or any other Transaction Document (as defined in the Securities Purchase Agreement) or any other agreement, document, certificate or other instrument delivered in connection with the transactions contemplated hereby and thereby to which the Holder is a party, except, in the case of a failure to pay Interest when and as due, in which case only if such failure continues for a period of at least three (3) Trading Days;

(vi) the occurrence of any default under, redemption of or acceleration prior to maturity of more than $300,000 of Indebtedness (as defined in Section 3(s) of the Securities Purchase Agreement) of the Company or any of its Subsidiaries (as defined in Section 3(a) of the Securities Purchase Agreement) other than with respect to any Other Notes;

(vii) the Company or any of its Subsidiaries, pursuant to or within the meaning of Title 11, U.S. Code, the Bankruptcy and Insolvency Act (Canada), the Companies Creditors Arrangement Act (Canada) or any similar Federal, foreign or state law for the relief of debtors (collectively, "Bankruptcy Law”), (A) commences a voluntary case, (B) consents to the entry of an order for relief against it in an involuntary case, (C) consents to the appointment of a receiver, interim receiver, receiver and manager, trustee, assignee, liquidator or similar official (a “Custodian”), (D) makes a general assignment for the benefit of its creditors or (E) admits in writing that it is generally unable to pay its debts as they become due;

(viii) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that (A) is for relief against the Company or any of its Subsidiaries in an involuntary case, (B) appoints a Custodian of the Company or any of its Subsidiaries or (C) orders the liquidation of the Company or any of its Subsidiaries;

(ix) a final judgment or judgments for the payment of money aggregating in excess of $1,000,000 are rendered against the Company or any of its Subsidiaries and which judgments are not, within sixty (60) days after the entry thereof, bonded, discharged or stayed pending appeal, or are not discharged within sixty (60) days after the expiration of such stay; provided, however, that any judgment which is covered by insurance or an indemnity from a credit worthy party shall not be included in calculating the $1,000,000 amount set forth above so long as the Company provides the Holder a written statement from such insurer or indemnity provider (which written statement shall be reasonably satisfactory to the Holder) to the effect that such judgment is covered by insurance or an indemnity and the Company will receive the proceeds of such insurance or indemnity within thirty (30) days of the issuance of such judgment;

(x) other than as set forth in item (xi) below, the Company breaches any representation, warranty, covenant or other term or condition of any Transaction Document, except, in the case of a breach of a covenant which is curable, only if such breach continues for a period of at least fifteen (15) consecutive Trading Days after notice thereof by the Holder or any holder of Other Notes; provided, however, that no notice shall be required to be made to the Company with respect to any breach of any representation, warranty, covenant or other term or condition of the Security Documents;

(xi) any breach or failure in any respect to comply with either of Sections 8 or 15 of this Note; or

(xii) any Event of Default (as defined in the Other Notes) occurs with respect to any Other Notes.

(b) Redemption Right. Promptly after the occurrence of an Event of Default with respect to this Note or any Other Note, the Company shall deliver written notice thereof via facsimile and overnight courier (an “Event of Default Notice”) to the Holder. At any time after the earlier of the Holder’s receipt of an Event of Default Notice and the Holder becoming aware of an Event of Default, the Holder may require the Company to redeem all or any portion of this Note by delivering written notice thereof (the “Event of Default Redemption Notice”) to the Company, which Event of Default Redemption Notice shall indicate the portion of this Note the Holder is electing to redeem. Each portion of this Note subject to redemption by the Company pursuant to this Section 4(b) shall be redeemed by the Company at a price equal to the greater of (i) the product of (x) the Conversion Amount to be redeemed and (y) the Redemption Premium and (ii) the product of (A) the Conversion Rate with respect to such Conversion Amount in effect at such time as the Holder delivers an Event of Default Redemption Notice and (B) the Closing Sale Price of the Common Shares on the date immediately preceding such Event of Default (the “Event of Default Redemption Price”). Redemptions required by this Section 4(b) shall be made in accordance with the provisions of Section 13. In the event of a partial redemption of this Note pursuant hereto, the principal amount redeemed shall be deducted from the Installment Amounts relating to the applicable Installment Dates as set forth in the Event of Default Redemption Notice.

(a) Assumption. The Company shall not enter into or be party to a Fundamental Transaction unless the Successor Entity (if other than the Company) assumes in writing all of the obligations of the Company under this Note and the other Transaction Documents in accordance with the provisions of this Section 5(a) pursuant to written agreements in form and substance satisfactory to the Required Holders and approved by the Required Holders prior to such Fundamental Transaction, including agreements to deliver to each holder of Notes in exchange for such Notes a security of the Successor Entity evidenced by a written instrument substantially similar in form and substance to the Notes, including, without limitation, having a principal amount and interest rate equal to the principal amounts and the interest rates of the Notes held by such holder and having similar ranking to the Notes, and satisfactory to the Required Holders. Upon the occurrence of any Fundamental Transaction, the Successor Entity shall succeed to, and be substituted for (so that from and after the date of such Fundamental Transaction, the provisions of this Note referring to the “Company” shall refer instead to the Successor Entity), and may exercise every right and power of the Company and shall assume all of the obligations of the Company under this Note with the same effect as if such Successor Entity had been named as the Company herein. Upon consummation of the Fundamental Transaction, the Successor Entity (if other than the Company) shall deliver to the Holder confirmation that there shall be issued upon conversion or redemption of this Note at any time after the consummation of the Fundamental Transaction, in lieu of the Company’s Common Shares (or other securities, cash, assets or other property) purchasable upon the conversion or redemption of the Notes prior to such Fundamental Transaction, such shares, securities, cash, assets or any other property whatsoever (including warrants or other purchase or subscription rights) which the Holder would have been entitled to receive upon the happening of such Fundamental Transaction had this Note been converted immediately prior to such Fundamental Transaction, as adjusted in accordance with the provisions of this Note; provided, however, that in the event that, pursuant to the terms of the Fundamental Transaction, the holders of Common Shares may elect the consideration to be received in exchange for the Common Shares in the such Fundamental Transaction, the Holder shall elect, within the same time periods as provided to the holders of Common Shares, the kind or amount of such shares, securities, cash, assets or any other property (including warrants or other purchase or subscription rights) that the Holder will, following the consummation of such transaction, be entitled to receive upon conversion or redemption; provided, further, however, that no such election by the Holder shall be construed to require the conversion or redemption of this Note in connection with such Fundamental Transaction. If the Holder is required to make any election of the kind described in the foregoing sentence, the Company shall deliver to the Holder all documentation, informational materials and election forms relating to such Fundamental Transaction contemporaneously with the delivery of such documentation, materials and forms to the holders of the Common Shares. The provisions of this Section shall apply similarly and equally to successive Fundamental Transactions and shall be applied without regard to any limitations on the conversion or redemption of this Note.

(b) Holder Redemption Right. No sooner than fifteen (15) days nor later than ten (10) days prior to the consummation of a Change of Control, but not prior to the public announcement of such Change of Control, the Company shall deliver written notice thereof via facsimile and overnight courier to the Holder (a “Change of Control Notice”); provided that in the event of a Change of Control covered by Section 5(c)(i), the Company shall deliver a Company Change of Control Redemption Notice in lieu of a Change of Control Notice. At any time during the period beginning after the Holder’s receipt of a Change of Control Notice and ending on the date of the consummation of such Change of Control (or, in the event a Change of Control Notice is not delivered at least ten (10) days prior to a Change of Control, at any time on or after the date which is ten (10) days prior to a Change of Control and ending ten (10) days after the consummation of such Change of Control), the Holder may require the Company to redeem all or any portion of this Note by delivering written notice thereof (“Change of Control Redemption Notice”) to the Company, which Change of Control Redemption Notice shall indicate the Conversion Amount the Holder is electing to redeem. The portion of this Note subject to redemption pursuant to this Section 5 shall be redeemed by the Company at a price equal to the greater of (i) the product of (x) the Conversion Amount being redeemed and (y) the quotient determined by dividing (A) the Closing Sale Price of the Common Shares immediately following the public announcement of such proposed Change of Control by (B) the Conversion Price and (ii) 115% of the Conversion Amount being redeemed (the “Holder Change of Control Redemption Price”). Redemptions required by this Section 5 shall be made in accordance with the provisions of Section 13. In the event of a partial redemption of this Note pursuant hereto, the principal amount redeemed shall be deducted from the Installment Amounts relating to the applicable Installment Dates as set forth in the Change of Control Redemption Notice.

(c) (i) Company Redemption Obligation. Notwithstanding the foregoing provisions of this Section 5, in the event of a Change of Control where the Successor Entity (not including its Parent Entity) is not a publicly traded entity whose common shares or equivalent equity security are quoted or listed for trading on an Eligible Market, then the Company shall, simultaneously with the consummation of such Change of Control, redeem this Note (a “Company Change of Control Redemption”), in whole and not in part, at a price equal to 125% of the Conversion Amount (the "Company Change of Control Redemption Price” and, together with the Holder Change of Control Redemption Price, a “Change of Control Redemption Price”). No sooner than fifteen (15) days nor later than ten (10) days prior to the consummation of any Change of Control described in the foregoing sentence, but not prior to the public announcement of such Change of Control, the Company shall provide notice (the “Company Change of Control Redemption Notice”) of a Company Change of Control Redemption in writing to the Holder. The Company Change of Control Redemption Notice shall state (x) the anticipated Trading Day the Change of Control shall be consummated (the “Company Change of Control Redemption Date”), (y) the aggregate Conversion Amount of the Notes subject to redemption from all the holders of the Notes pursuant to this Section 5(c) and (z) the Company Change of Control Redemption Price that to be paid to such Holder on the Company Change of Control Redemption Date; provided, however, that in the event the Company Change of Control Redemption Date is changed from the anticipated date set forth in the Company Change of Control Redemption Notice, the Company shall inform the Holder in writing of the new Company Change of Control Redemption Date within one (1) Trading Day of the date on which the Company learns of such new date.

(ii) Pro Rata Redemption Requirement. If the Company delivers any Company Change of Control Redemption Notice to the Holder with respect to the full Conversion Amount of this Note pursuant to Section 5(c)(i), then it must simultaneously take the same action and in the same proportion with respect to the Other Notes.

(d) Redemptions required by this Section 5 shall have priority to payments to shareholders in connection with a Change of Control. Notwithstanding anything to the contrary in this Section 5, but subject to Section 3(d), until the Change of Control Redemption Price (together with any interest thereon) is paid in full, the Conversion Amount submitted for redemption under this Section 5(c) (together with any interest thereon) may be converted, in whole or in part, by the Holder into Common Shares pursuant to Section 3.

(a) Purchase Rights. If at any time the Company grants, issues or sells any Options, Convertible Securities or rights to purchase shares, warrants, securities or other property pro rata to all record holders of any class of Common Shares (the “Purchase Rights”), then the Holder will be entitled to acquire, upon the terms applicable to such Purchase Rights, the aggregate Purchase Rights which the Holder could have acquired if the Holder had held the number of Common Shares acquirable upon complete conversion of this Note (without taking into account any limitations or restrictions on the convertibility of this Note) immediately before the date on which a record is taken for the grant, issuance or sale of such Purchase Rights, or, if no such record is taken, the date as of which the record holders of Common Shares are to be determined for the grant, issue or sale of such Purchase Rights.

(b) Other Corporate Events. In addition to and not in substitution for any other rights hereunder, but subject to the Company’s obligation to redeem this Note pursuant to Section 5(c) hereof, prior to the consummation of any Fundamental Transaction pursuant to which holders of Common Shares are entitled to receive securities or other assets with respect to or in exchange for Common Shares (a “Corporate Event”), the Company shall make appropriate provision to insure that the Holder will thereafter have the right to receive upon a conversion of this Note, (i) in addition to the Common Shares receivable upon such conversion, such securities or other assets to which the Holder would have been entitled with respect to such Common Shares had such Common Shares been held by the Holder upon the consummation of such Corporate Event (without taking into account any limitations or restrictions on the convertibility of this Note) or (ii) in lieu of the Common Shares otherwise receivable upon such conversion, such securities or other assets received by the holders of Common Shares in connection with the consummation of such Corporate Event in such amounts as the Holder would have been entitled to receive had this Note initially been issued with conversion rights for the form of such consideration (as opposed to Common Shares) at a conversion rate for such consideration commensurate with the Conversion Rate. Provision made pursuant to the preceding sentence shall be in a form and substance satisfactory to the Required Holders. The provisions of this Section shall apply similarly and equally to successive Corporate Events and shall be applied without regard to any limitations on the conversion or redemption of this Note.

(a) Adjustment of Conversion Price upon Issuance of Common Shares. If and whenever on or after the Subscription Date until the first (1^st) anniversary of the Subscription Date, the Company issues or sells, or in accordance with this Section 7(a) is deemed to have issued or sold, any Common Shares (including the issuance or sale of Common Shares owned or held by or for the account of the Company, but excluding Common Shares deemed to have been issued or sold by the Company in connection with any Excluded Security) for a consideration per share (the “New Issuance Price”) less than a price (the “Applicable Price”) equal to the Conversion Price in effect immediately prior to such issue or sale (the foregoing a “Dilutive Issuance”), then immediately after such Dilutive Issuance, the Conversion Price then in effect shall be reduced to an amount equal to the New Issuance Price. For purposes of determining the adjusted Conversion Price under this Section 7(a), the following shall be applicable:

(i) Issuance of Options. If the Company in any manner grants or sells any Options and the lowest price per share for which one Common Share is issuable upon the exercise of any such Option or upon conversion or exchange or exercise of any Convertible Securities issuable upon exercise of such Option is less than the Applicable Price, then such Common Share shall be deemed to be outstanding and to have been issued and sold by the Company at the time of the granting or sale of such Option for such price per share. For purposes of this Section 7(a)(i), the “lowest price per share for which one Common Share is issuable upon the exercise of any such Option or upon conversion or exchange or exercise of any Convertible Securities issuable upon exercise of such Option” shall be equal to the sum of the lowest amounts of consideration (if any) received or receivable by the Company with respect to any one Common Share upon granting or sale of the Option, upon exercise of the Option and upon conversion or exchange or exercise of any Convertible Security issuable upon exercise of such Option. No further adjustment of the Conversion Price shall be made upon the actual issuance of such Common Shares or of such Convertible Securities upon the exercise of such Options or upon the actual issuance of such Common Shares upon conversion or exchange or exercise of such Convertible Securities.

(ii) Issuance of Convertible Securities. If the Company in any manner issues or sells any Convertible Securities and the lowest price per share for which one Common Share is issuable upon such conversion or exchange or exercise thereof is less than the Applicable Price, then such Common Share shall be deemed to be outstanding and to have been issued and sold by the Company at the time of the issuance of sale of such Convertible Securities for such price per share. For the purposes of this Section 7(a)(ii), the “price per share for which one Common Share is issuable upon such conversion or exchange or exercise” shall be equal to the sum of the lowest amounts of consideration (if any) received or receivable by the Company with respect to any one Common Share upon the issuance or sale of the Convertible Security and upon the conversion or exchange or exercise of such Convertible Security. No further adjustment of the Conversion Price shall be made upon the actual issuance of such Common Shares upon conversion or exchange or exercise of such Convertible Securities, and if any such issue or sale of such Convertible Securities is made upon exercise of any Options for which adjustment of the Conversion Price had been or are to be made pursuant to other provisions of this Section 7(a), no further adjustment of the Conversion Price shall be made by reason of such issue or sale.

(iii) Change in Option Price or Rate of Conversion. If the purchase price provided for in any Options, the additional consideration, if any, payable upon the issue, conversion, exchange or exercise of any Convertible Securities, or the rate at which any Convertible Securities are convertible into or exchangeable or exercisable for Common Shares changes at any time, the Conversion Price in effect at the time of such change shall be adjusted to the Conversion Price which would have been in effect at such time had such Options or Convertible Securities provided for such changed purchase price, additional consideration or changed conversion rate, as the case may be, at the time initially granted, issued or sold. For purposes of this Section 7(a)(iii), if the terms of any Option or Convertible Security that was outstanding as of the Subscription Date are changed in the manner described in the immediately preceding sentence, then such Option or Convertible Security and the Common Shares deemed issuable upon exercise, conversion or exchange thereof shall be deemed to have been issued as of the date of such change. No adjustment shall be made if such adjustment would result in an increase of the Conversion Price then in effect.

(iv) Calculation of Consideration Received. In case any Option is issued in connection with the issue or sale of other securities of the Company, together comprising one integrated transaction in which no specific consideration is allocated to such Options by the parties thereto, the Options will be deemed to have been issued for a consideration of $.01. If any Common Shares, Options or Convertible Securities are issued or sold or deemed to have been issued or sold for cash, the consideration received therefor will be deemed to be the net amount received by the Company therefor. If any Common Shares, Options or Convertible Securities are issued or sold for a consideration other than cash, the amount of the consideration other than cash received by the Company will be the fair value of such consideration, except where such consideration consists of securities, in which case the amount of consideration received by the Company will be the Closing Sale Price of such securities on the date of receipt. If any Common Shares, Options or Convertible Securities are issued to the owners of the non-surviving entity in connection with any merger in which the Company is the surviving entity, the amount of consideration therefor will be deemed to be the fair value of such portion of the net assets and business of the non-surviving entity as is attributable to such Common Shares, Options or Convertible Securities, as the case may be. The fair value of any consideration other than cash or securities will be determined jointly by the Company and the Required Holders. If such parties are unable to reach agreement within ten (10) days after the occurrence of an event requiring valuation (the “Valuation Event”), the fair value of such consideration will be determined within five (5) Trading Days after the tenth (10^th) day following the Valuation Event by an independent, reputable appraiser jointly selected by the Company and the Required Holders. The determination of such appraiser shall be deemed binding upon all parties absent manifest error and the fees and expenses of such appraiser shall be borne by the Company.

(v) Record Date. If the Company takes a record of the holders of Common Shares for the purpose of entitling them (A) to receive a dividend or other distribution payable in Common Shares, Options or in Convertible Securities or (B) to subscribe for or purchase Common Shares, Options or Convertible Securities, then such record date will be deemed to be the date of the issue or sale of the Common Shares deemed to have been issued or sold upon the declaration of such dividend or the making of such other distribution or the date of the granting of such right of subscription or purchase, as the case may be.

(b) Adjustment of Conversion Price upon Subdivision or Combination of Common Shares. If the Company at any time on or after the Subscription Date subdivides (by any share split, share dividend, recapitalization or otherwise) one or more classes of its outstanding Common Shares into a greater number of shares, the Conversion Price in effect immediately prior to such subdivision will be proportionately reduced. If the Company at any time on or after the Subscription Date combines (by combination, reverse share split or otherwise) one or more classes of its outstanding Common Shares into a smaller number of shares, the Conversion Price in effect immediately prior to such combination will be proportionately increased.

(c) Other Events. If any event occurs of the type contemplated by the provisions of this Section 7 but not expressly provided for by such provisions (including, without limitation, the granting of share appreciation rights, phantom share rights or other rights with equity features), then the Company’s Board of Directors will make an appropriate adjustment in the Conversion Price so as to protect the rights of the Holder under this Note; provided that no such adjustment will increase the Conversion Price as otherwise determined pursuant to this Section 7.

(a) General. Subject to and in accordance with the terms of this Section 8, on each applicable Installment Date, the Company shall pay to the Holder of this Note the Installment Amount as of such Installment Date by the combination of any of the following, (i) provided that during the period commencing with the Company Installment Notice (as defined below) through the applicable Installment Date, the Equity Conditions have been satisfied (or waived in writing by the Holder), requiring the conversion of a portion of the applicable Installment Amount, in whole or in part, in accordance with this Section 8 (a “Company Conversion”), and/or (ii) redeeming the applicable Installment Amount, in whole or in part, in accordance with this Section 8 (a “Company Redemption”); provided that all of the outstanding applicable Installment Amount as of each such Installment Date must be converted and/or redeemed by the Company on the applicable Installment Date, subject to the provisions of this Section 8. On or prior to the Installment Notice Due Date, the Company shall deliver written notice (each, a “Company Installment Notice” and, in the event a Company Redemption is elected in such notice, together with the Event of Default Redemption Notice, Change of Control Redemption Notice and the Company Change of Control Redemption Notice, the "Redemption Notices” and each a “Redemption Notice”), to the Holder which Company Installment Notice shall state (i) the portion, if any, of the applicable Installment Amount which the Company elects to convert pursuant to a Company Conversion, which amount when added to the Company Redemption Amount must equal the applicable Installment Amount (the “Company Conversion Amount”), (ii) the portion, if any, of the applicable Installment Amount which the Company elects to redeem pursuant to a Company Redemption (the “Company Redemption Amount”), which amount when added to the Company Conversion Amount must equal the applicable Installment Amount and (iii) if the Company has elected, in whole or in part, a Company Conversion, then the Company Installment Notice shall certify that the Equity Conditions have been satisfied as of the date of the Company Installment Notice. If the Company does not timely deliver a Company Installment Notice in accordance with this Section 8(a), then the “Company Redemption Amount” and the “Company Conversion Amount” with respect to such Installment Date shall be in such amounts and proportions as the Holder shall designate in writing (the “Holder Installment Notice”), to the Company in its sole discretion and the Company shall be deemed to have delivered a Company Installment Notice setting forth such amounts; provided, however, that if such Holder Installment Notice designates a Company Conversion Amount the Company shall certify in writing to the Holder within two (2) Trading Days of receipt of such Holder Installment Notice whether or not the Equity Conditions have been satisfied; provided, further, however that if such conditions have not been satisfied the Holder may thereafter (x) elect to require the Company to pay the entire Installment Amount as a Company Redemption or (y) waive the Equity Conditions and require the Company to pay the Installment Amount in the manner set forth in the Holder Installment Notice. Each Company Installment Notice whether actually given or deemed given shall be irrevocable. Except as expressly provided in this Section 8(a), the Company shall redeem and convert the applicable Installment Amount of this Note pursuant to this Section 8 and the corresponding Installment Amounts of the Other Notes pursuant to the corresponding provisions of the Other Notes in the same ratio of the Installment Amount being redeemed and converted hereunder. The Company Redemption Amount (whether set forth in the Company Installment Notice or by operation of this Section 8) shall be redeemed in accordance with Section 8(b) and the Company Conversion Amount shall be converted in accordance with Section 8(c). Notwithstanding the foregoing, unless the Company is given notice to the contrary by the Holder, if the arithmetic average of the Weighted Average Price of the Common Shares during the applicable Company Conversion Measuring Period is greater than the Conversion Price, then the Company shall be deemed to have elected a Company Conversion in the Company Installment Notice as to the entire applicable Installment Amount.

(b) Mechanics of Company Redemption. If the Company elects, or is deemed to have elected, a Company Redemption in accordance with Section 8(a), then the Company Redemption Amount, if any, which is to be paid to the Holder on the applicable Installment Date shall be redeemed by the Company on such Installment Date, and the Company shall pay to the Holder on such Installment Date, by wire transfer of immediately available funds, an amount in cash (the “Company Installment Redemption Price” and, together with the Event of Default Redemption Price, Change of Control Redemption Price and the Company Change of Control Redemption Price, the “Redemption Prices” and each a “Redemption Price”) equal to 100% of the Company Redemption Amount. If the Company fails to redeem the Company Redemption Amount on the applicable Installment Date by payment of the Company Installment Redemption Price on such date, then at the option of the Holder designated in writing to the Company (any such designation, a “Conversion Notice” for purposes of this Note), the Holder may require the Company to convert all or any part of the Company Redemption Amount at the Company Conversion Price. Conversions required by this Section 8(b) shall be made in accordance with the provisions of Section 3(c). Notwithstanding anything to the contrary in this Section 8(b), but subject to Section 3(d), until the Company Installment Redemption Price (together with any interest thereon) is paid in full, the Company Redemption Amount (together with any interest thereon) may be converted, in whole or in part, by the Holder into Common Shares pursuant to Section 3. In the event the Holder elects to convert all or any portion of the Company Redemption Amount prior to the applicable Installment Date as set forth in the immediately preceding sentence, the Company Redemption Amount so converted shall be deducted from the Installment Amount to be paid on such Installment Date.

(c) Mechanics of Company Conversion. Subject to Section 3(d), if the Company delivers a Company Installment Notice and elects, or is deemed to have elected, in whole or in part, a Company Conversion in accordance with Section 8(a), then the applicable Company Conversion Amount, if any, which remains outstanding shall be converted as of the applicable Installment Date by converting on such Installment Date such Company Conversion Amount at the Company Conversion Price; provided that the Equity Conditions have been satisfied (or waived in writing by the Holder) on such Installment Date. If the Equity Conditions are not satisfied (or waived in writing by the Holder) on such Installment Date, then at the option of the Holder designated in writing to the Company, the Holder may require the Company to do any one or more of the following: (i) the Company shall redeem all or any part designated by the Holder of the unconverted Company Conversion Amount (such designated amount is referred to as the “First Redemption Amount”) on such Installment Date and the Company shall pay to the Holder on such Installment Date, by wire transfer of immediately available funds, an amount in cash equal to 120% of such First Redemption Amount, or (ii) the Company Conversion shall be null and void with respect to all or any part designated by the Holder of the unconverted Company Conversion Amount and the Holder shall be entitled to all the rights of a holder of this Note with respect to such amount of the Company Conversion Amount; provided, however, that the Conversion Price for such unconverted Company Conversion Amount shall thereafter be adjusted to equal the lesser of (A) the Company Conversion Price as in effect on the date on which the Holder voided the Company Conversion and (B) the Company Conversion Price as in effect on the date on which the Holder delivers a Conversion Notice relating thereto. If the Company fails to redeem any First Redemption Amount on or before the applicable Installment Date by payment of such amount on the applicable Installment Date, then the Holder shall have the rights set forth in Section 13(a) as if the Company failed to pay the applicable Company Redemption Price and all other rights under this Note (including, without limitation, such failure constituting an Event of Default described in Section 4(a)(xi)). Notwithstanding anything to the contrary in this Section 8(c), but subject to 3(d), until the Company delivers Common Shares representing the Company Conversion Amount to the Holder, the Company Conversion Amount may be converted by the Holder into Common Shares pursuant to Section 3. In the event the Holder elects to convert the Company Conversion Amount prior to the applicable Installment Date as set forth in the immediately preceding sentence, the Company Conversion Amount so converted shall be deducted from the Installment Amount to be paid on such Installment Date.

(a) Mandatory Conversion. If at any time from and after the one-year anniversary of the Effectiveness Time (the “Mandatory Conversion Eligibility Date”), (i) the Closing Sale Price of the Common Shares equals or exceeds 225% of the Conversion Price on the Issuance Date (subject to appropriate adjustments for share splits, share dividends, share combinations and other similar transactions after the Subscription Date) for each of any twenty (20) consecutive Trading Days following the Mandatory Conversion Eligibility Date (the “Mandatory Conversion Measuring Period”) and (ii) the Equity Conditions shall have been satisfied (or waived in writing by the Holder, provided that the Holder may not waive the provisions of Section 3(d)(ii)), during the period commencing on the Mandatory Conversion Notice Date through the applicable Mandatory Conversion Date (each, as defined below), the Company shall have the right to require the Holder to convert all, but not less than all, of the Conversion Amount then remaining under this Note plus the Present Value of Interest as designated in the Mandatory Conversion Notice (as defined below) into fully paid, validly issued and non-assessable Common Shares in accordance with Section 3(c) hereof at the Conversion Rate in effect on the Mandatory Conversion Date (as defined below) (a “Mandatory Conversion”) or, at the Company’s option and solely with respect to the Present Value of Interest, cash or a combination of Common Shares and cash. The Company may exercise its right to require conversion under this Section 9(a), by delivering within not more than two (2) Trading Days following the end of such Mandatory Conversion Measuring Period a written notice thereof by facsimile and overnight courier to all, but not less than all, of the holders of Notes and the Transfer Agent (the “Mandatory Conversion Notice” and the date all of the holders received such notice by facsimile is referred to as the “Mandatory Conversion Notice Date”). The Mandatory Conversion Notice shall be irrevocable. The Mandatory Conversion Notice shall state (i) the Trading Day selected for the Mandatory Conversion in accordance with Section 9(a), which Trading Day shall be at least ten (10) Trading Days but not more than sixty (60) Trading Days following the Mandatory Conversion Notice Date (the “Mandatory Conversion Date”), (ii) the aggregate Conversion Amount of the Notes subject to mandatory conversion from all of the holders of the Notes pursuant to this Section 9 (and analogous provisions under the Other Notes), (iii) the number of Common Shares to be issued to, and the Present Value of Interest to be paid to, such Holder on the Mandatory Conversion Date and (iv) the portion, if any, of the Present Value of Interest that shall be paid in cash and the portion, if any, that shall be paid in Common Shares.

(b) Pro Rata Conversion Requirement. If the Company elects to cause a conversion of any Conversion Amount of this Note pursuant to Section 9(a), then it must simultaneously take the same action in the same proportion with respect to the Other Notes. All Conversion Amounts converted by the Holder after the Mandatory Conversion Notice Date shall reduce the Conversion Amount of this Note required to be converted on the Mandatory Conversion Date. If the Company has elected a Mandatory Conversion, the mechanics of conversion set forth in Section 3(c) shall apply, to the extent applicable, as if the Company and the Transfer Agent had received from the Holder on the Mandatory Conversion Date a Conversion Notice with respect to the Conversion Amount being converted pursuant to the Mandatory Conversion.

(10) SECURITY. This Note and the Other Notes are secured to the extent and in the manner set forth in the Security Documents (as defined in the Securities Purchase Agreement).

(11) NONCIRCUMVENTION. The Company hereby covenants and agrees that the Company will not, by amendment of its Articles of Incorporation, Bylaws or through any reorganization, transfer of assets, consolidation, merger, scheme of arrangement, dissolution, issue or sale of securities, or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of this Note, and will at all times in good faith carry out all of the provisions of this Note and take all action as may be required to protect the rights of the Holder of this Note.

(a) Reservation. The Company shall have sufficient authorized and unissued Common Shares for each of the Notes equal to the number of Common Shares necessary to effect the conversion at the Conversion Rate with respect to the Conversion Amount of each such Note as of the Issuance Date. So long as any of the Notes are outstanding, the Company shall take all action necessary to have available out of its authorized and unissued Common Shares, solely for the purpose of effecting the conversion of the Notes, the number of Common Shares as shall from time to time be necessary to effect the conversion of all of the Notes then outstanding; provided that at no time shall the number of Common Shares so available be less than the number of shares required to be reserved by the previous sentence (without regard to any limitations on conversions) (the "Required Amount”).

(b) Insufficient Authorized Shares. If at any time while any of the Notes remain outstanding the Company does not have a sufficient number of authorized and unissued Common Shares to satisfy its obligation to have available for issuance upon conversion of the Notes at least a number of Common Shares equal to the Required Amount (an “Authorized Share Failure”), then the Company shall immediately take all action necessary to increase the Company’s authorized Common Shares to an amount sufficient to allow the Company to reserve the Required Amount for the Notes then outstanding.

(a) Mechanics. The Company shall deliver the applicable Event of Default Redemption Price to the Holder within five (5) Trading Days after the Company’s receipt of the Holder’s Event of Default Redemption Notice. If the Holder has submitted a Change of Control Redemption Notice in accordance with Section 5(b), the Company shall deliver the applicable Change of Control Redemption Price to the Holder concurrently with the consummation of such Change of Control if such notice is received prior to the consummation of such Change of Control and within five (5) Trading Days after the Company’s receipt of such notice otherwise. The Company shall deliver the applicable Company Installment Redemption Price to the Holder on the applicable Installment Date. In the event of a redemption of less than all of the Conversion Amount of this Note, the Company shall promptly cause to be issued and delivered to the Holder a new Note (in accordance with Section 19(d)) representing the outstanding Principal which has not been redeemed. In the event that the Company does not pay the applicable Redemption Price to the Holder within the time period required, at any time thereafter and until the Company pays such unpaid Redemption Price in full, the Holder shall have the option, in lieu of redemption, to require the Company to promptly return to the Holder all or any portion of this Note representing the Conversion Amount that was submitted for redemption and for which the applicable Redemption Price has not been paid. Upon the Company’s receipt of such notice, (x) the Redemption Notice shall be null and void with respect to such Conversion Amount, (y) the Company shall immediately return this Note, or issue a new Note (in accordance with Section 19(d)) to the Holder representing such Conversion Amount and (z) the Conversion Price of this Note or such new Notes shall be adjusted to the lesser of (A) the Conversion Price as in effect on the date on which the Redemption Notice is voided and (B) the lowest Closing Bid Price of the Common Shares during the period beginning on and including the date on which the Redemption Notice is delivered to the Company and ending on and including the date on which the Redemption Notice is voided.

(b) Redemption by Other Holders. Upon the Company’s receipt of notice from any of the holders of the Other Notes for redemption or repayment as a result of an event or occurrence substantially similar to the events or occurrences described in Section 4(b) or Section 5(b) (each, an “Other Redemption Notice”), the Company shall immediately forward to the Holder by facsimile a copy of such notice. If the Company receives a Redemption Notice and one or more Other Redemption Notices, during the seven (7) Trading Day period beginning on and including the date which is three (3) Trading Days prior to the Company’s receipt of the Holder’s Redemption Notice and ending on and including the date which is three (3) Trading Days after the Company’s receipt of the Holder’s Redemption Notice and the Company is unable to redeem all principal, interest and other amounts designated in such Redemption Notice and such Other Redemption Notices received during such seven (7) Trading Day period, then the Company shall redeem a pro rata amount from each holder of the Notes (including the Holder) based on the principal amount of the Notes submitted for redemption pursuant to such Redemption Notice and such Other Redemption Notices received by the Company during such seven (7) Trading Day period.

(14) VOTING RIGHTS. The Holder shall have no voting rights as the holder of this Note, except as required by law, the Canada Business Corporations Act and as expressly provided in this Note, or any other Transaction Documents.

(a) Rank. All payments due under this Note (i) shall rank pari passu with all Other Notes and (ii) shall be senior to all other Indebtedness of the Company and its Subsidiaries.

(b) Incurrence of Indebtedness. So long as this Note is outstanding, the Company shall not, and the Company shall not permit any of its Subsidiaries to, directly or indirectly, incur or guarantee, assume or suffer to exist any Indebtedness, other than (i) the Indebtedness evidenced by this Note and the Other Notes and (ii) Permitted Indebtedness.

(c) Existence of Liens. So long as this Note is outstanding, the Company shall not, and the Company shall not permit any of its Subsidiaries to, directly or indirectly, allow or suffer to exist any mortgage, lien, pledge, charge, security interest or other encumbrance upon or in any property or assets (including accounts and contract rights) owned by the Company or any of its Subsidiaries (collectively, “Liens”) other than Permitted Liens.

(d) Restricted Payments. The Company shall not, and the Company shall not permit any of its Subsidiaries to, directly or indirectly, redeem, defease, repurchase, repay or make any payments in respect of, by the payment of cash or cash equivalents (in whole or in part, whether by way of open market purchases, tender offers, private transactions or otherwise), all or any portion of any Permitted Indebtedness whether by way of payment in respect of principal of (or premium, if any) or interest on such Indebtedness if at the time such payment is due or is otherwise made or, after giving effect to such payment, an event constituting, or that with the passage of time and without being cured would constitute, an Event of Default has occurred and is continuing.

(e) Financial Covenants. The Company shall maintain, for each Calendar Quarter, (i) LTM Tested Revenues equal to or exceeding the applicable LTM Tested Revenues Threshold, (ii) Quarterly Revenues equal to or exceeding the applicable Quarterly Revenues Threshold, (iii) Gross Margin equal to or exceeding the applicable Tested Gross Margin Threshold and (iv) Cash Balance equal to or exceeding the applicable Cash Balance Threshold; provided, however, that the Company shall not be required to satisfy the LTM Tested Revenues Threshold until December 31, 2006 (for the measurement period beginning on December 31, 2005).

(i) The Company shall announce whether it has met the Cash Balance Threshold (the “Cash Balance Announcement”) for each Calendar Quarter no later than the ten (10^th) day after the end of each Calendar Quarter and such announcement shall include the amount of the Company’s Cash Balance. On the date of such announcement, the Company shall also provide to the Holders a certification, executed on behalf of the Company by its Chief Financial Officer, as to the amount of the Cash Balance as of the end of, and for, the Calendar Quarter to which such Cash Balance Announcement relates.

(ii) The Company shall announce its operating results (the “Operating Results”) for each Calendar Quarter no later than the forty-fifth (45^th) day after the end of each Calendar Quarter and such announcement shall include the amount of the Company’s LTM Tested Revenues, Quarterly Revenues and Gross Margin. On the date of such announcement, the Company shall also provide to the Holders a certification, executed on behalf of the Company by its Chief Financial Officer, as to the amount of the LTM Tested Revenues, Quarterly Revenues and Gross Margin as of the end of, and for, the Calendar Quarter to which such Operating Results relate.

(f) SoftScan Approval. The Company shall have submitted for SoftScan’s regulatory approval by June 30, 2006 with the appropriate health regulatory authority in Canada or the United States of America.

(16) PARTICIPATION. The Holder, as the holder of this Note, shall be entitled to receive such dividends paid and distributions made to the holders of Common Shares to the same extent as if the Holder had converted this Note into Common Shares (without regard to any limitations on conversion herein or elsewhere) and had held such Common Shares on the record date for such dividends and distributions. Payments under the preceding sentence shall be made concurrently with the dividend or distribution to the holders of Common Shares. Notwithstanding the foregoing, nothing in this Section 16 shall be deemed to prevent the Company from accruing dividends (which dividends remain unpaid) on any preferred shares of the Company.

(17) VOTE TO ISSUE, OR CHANGE THE TERMS OF, NOTES. The affirmative vote at a meeting duly called for such purpose or the written consent without a meeting of the Required Holders shall be required for any change or amendment to this Note or the Other Notes.

(18) TRANSFER. This Note and any Common Shares issued upon conversion of this Note may be offered, sold, assigned or transferred by the Holder without the consent of the Company, subject only to the provisions of Section 2(f) of the Securities Purchase Agreement.

(a) Transfer. If this Note is to be transferred, the Holder shall surrender this Note to the Company, whereupon the Company will forthwith issue and deliver upon the order of the Holder a new Note (in accordance with Section 19(d)), registered as the Holder may request, representing the outstanding Principal being transferred by the Holder and, if less then the entire outstanding Principal is being transferred, a new Note (in accordance with Section 19(d)) to the Holder representing the outstanding Principal not being transferred. The Holder and any assignee, by acceptance of this Note, acknowledge and agree that, by reason of the provisions of Section 3(c)(iii) following conversion or redemption of any portion of this Note, the outstanding Principal represented by this Note may be less than the Principal stated on the face of this Note.

(b) Lost, Stolen or Mutilated Note. Upon receipt by the Company of evidence reasonably satisfactory to the Company of the loss, theft, destruction or mutilation of this Note, and, in the case of loss, theft or destruction, of any indemnification undertaking by the Holder to the Company in customary form and, in the case of mutilation, upon surrender and cancellation of this Note, the Company shall execute and deliver to the Holder a new Note (in accordance with Section 19(d)) representing the outstanding Principal.

(c) Note Exchangeable for Different Denominations. This Note is exchangeable, upon the surrender hereof by the Holder at the principal office of the Company, for a new Note or Notes (in accordance with Section 19(d) and in principal amounts of at least $100,000) representing in the aggregate the outstanding Principal of this Note, and each such new Note will represent such portion of such outstanding Principal as is designated by the Holder at the time of such surrender.

(d) Issuance of New Notes. Whenever the Company is required to issue a new Note pursuant to the terms of this Note, such new Note (i) shall be of like tenor with this Note, (ii) shall represent, as indicated on the face of such new Note, the Principal remaining outstanding (or in the case of a new Note being issued pursuant to Section 19(a) or Section 19(c), the Principal designated by the Holder which, when added to the principal represented by the other new Notes issued in connection with such issuance, does not exceed the Principal remaining outstanding under this Note immediately prior to such issuance of new Notes), (iii) shall have an issuance date, as indicated on the face of such new Note, which is the same as the Issuance Date of this Note, (iv) shall have the same rights and conditions as this Note, and (v) shall represent accrued and unpaid Interest on the Principal and Interest of this Note, from the Issuance Date.

(20) REMEDIES, CHARACTERIZATIONS, OTHER OBLIGATIONS, BREACHES AND INJUNCTIVE RELIEF. The remedies provided in this Note shall be cumulative and in addition to all other remedies available under this Note and any of the other Transaction Documents at law or in equity (including a decree of specific performance and/or other injunctive relief), and nothing herein shall limit the Holder’s right to pursue actual and consequential damages for any failure by the Company to comply with the terms of this Note. Amounts set forth or provided for herein with respect to payments, conversion and the like (and the computation thereof) shall be the amounts to be received by the Holder and shall not, except as expressly provided herein, be subject to any other obligation of the Company (or the performance thereof). The Company acknowledges that a breach by it of its obligations hereunder will cause irreparable harm to the Holder and that the remedy at law for any such breach may be inadequate. The Company therefore agrees that, in the event of any such breach or threatened breach, the Holder shall be entitled, in addition to all other available remedies, to an injunction restraining any breach, without the necessity of showing economic loss and without any bond or other security being required.

(21) PAYMENT OF COLLECTION, ENFORCEMENT AND OTHER COSTS. If (a) this Note is placed in the hands of an attorney for collection or enforcement or is collected or enforced through any legal proceeding or the Holder otherwise takes action to collect amounts due under this Note or to enforce the provisions of this Note or (b) there occurs any bankruptcy, reorganization, receivership of the Company or other proceedings affecting Company creditors’ rights and involving a claim under this Note, then the Company shall pay the costs incurred by the Holder for such collection, enforcement or action or in connection with such bankruptcy, reorganization, receivership or other proceeding, including, but not limited to, attorneys’ fees and disbursements.

(22) CONSTRUCTION; HEADINGS. This Note shall be deemed to be jointly drafted by the Company and all the Purchasers and shall not be construed against any person as the drafter hereof. The headings of this Note are for convenience of reference and shall not form part of, or affect the interpretation of, this Note.

(23) FAILURE OR INDULGENCE NOT WAIVER. No failure or delay on the part of the Holder in the exercise of any power, right or privilege hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such power, right or privilege preclude other or further exercise thereof or of any other right, power or privilege.

(24) DISPUTE RESOLUTION. In the case of a dispute as to the determination of the Closing Bid Price, the Closing Sale Price or the Weighted Average Price or the arithmetic calculation of the Conversion Rate or the Redemption Price, the Company shall submit the disputed determinations or arithmetic calculations via facsimile within one (1) Trading Day of receipt, or deemed receipt, of the Conversion Notice or Redemption Notice or other event giving rise to such dispute, as the case may be, to the Holder. If the Holder and the Company are unable to agree upon such determination or calculation within one (1) Trading Day of such disputed determination or arithmetic calculation being submitted to the Holder, then the Company shall, within one Trading Day submit via facsimile (a) the disputed determination of the Closing Bid Price, the Closing Sale Price or the Weighted Average Price to an independent, reputable investment bank selected by the Company and approved by the Holder or (b) the disputed arithmetic calculation of the Conversion Rate or the Redemption Price to the Company’s independent, outside accountant. The Company, at the Company’s expense shall cause the investment bank or the accountant, as the case may be, to perform the determinations or calculations and notify the Company and the Holder of the results no later than five (5) Trading Days from the time it receives the disputed determinations or calculations. Such investment bank’s or accountant’s determination or calculation, as the case may be, shall be binding upon all parties absent demonstrable error. In the event the Company’s determination or calculation is correct, the expenses of the investment bank or accountant, as the case may be, shall be borne by the Holder.

(a) Notices. Whenever notice is required to be given under this Note, unless otherwise provided herein, such notice shall be given in accordance with Section 9(f) of the Securities Purchase Agreement.
